Spec-to-Commit Go Microservice
Spec-Driven Development, Clean Hexagonal Architecture & Verifiable Audit Trails in Go
Architectural Overview
A reference microservice architecture in Go demonstrating the Spec-Driven Development lifecycle: transforming formal specifications directly into testable, production-ready code with zero drift.
The Specification Drift Problem
In distributed microservice environments, requirements and API specifications rapidly diverge from the codebase implementation. Hand-written models drift, integration tests become obsolete, and teams spend hundreds of hours diagnosing contract violations across microservice boundaries.
The Spec-to-Commit Solution
Built a clean hexagonal architecture in Go where code generation and contract validation are driven strictly by OpenSpec definitions. Domain rules, ports, and adapters are verified by automated contract tests before committing, ensuring 100% spec-to-code conformance and sub-5ms request latency.
Technologies & Architectural Patterns
Architectural Highlights
100% Conformance
Every endpoint, domain invariant, and error response is mathematically verified against the OpenSpec definition.
<5ms Request P99
Zero reflection, allocated memory buffers, and idiomatic Go concurrency deliver ultra-low latency response times.
Audit-Ready Commits
Cryptographically signed commits linked directly to approved architectural decision documents.
